For basic starters, you might try masturbating...

In the bath or shower.
While some may feel touching yourself is “dirty”, the use of water assures cleanliness. Controlling the hot or cold temperature of the water can create it’s own sensations. However, in the shower, you can experiment with the pressure of the water flow from the shower head and enjoy the “massage” sensations. And in the tub, while moving your body, you can enjoy the swish and swirl of the water around you; if you have whirlpool tub or jacuzzi all the better for you. Note: If your using a water jet (shower head, whirlpool), start at a safe distance from the stream of water, and make sure the jet is aimed at your genitals, not your rectum, or vagina. It is ok to pull your labia apart for a more powerful sensation.

In front of a mirror.
This is an excellent way to explore your body in more depth. You can view your body parts closely, not only feeling the swelling of your bud but now you can view it. Watching your own reaction to the pleasure you create can be very sensual.

In front of your partner.
What better way to show your partner what you like. You may be surprised just how much your partner gets turned on by watching you...

With a toy.
Take your time here and decide which toy turns you on the most or scares you the least. You really can’t go wrong with the basic vibrator, using gentle corkscrew massage and/or insertion motions. As you get comfortable using toys, experiment with different shapes, sizes, and style of toys and have some fun!

For the advance masturbators out there, you might try...

In the bath or shower
With your partner watching from the sidelines or in the water with you, lather up and massage your body while you wash. As you rinse the soap away, insert your fingers inside you, lick them and/or offer them to your partner to lick, suck, etc..

In front of a mirror.
Masturbate with a toy in front of the mirror and watch closely as your excitement builds. Not only will you feel your body’s juices flowing, you can now see them. Visual stimulation is quite arousing as you watch yourself be penetrated and you control the pace of insertion...and excitement.

In front of your partner.
While anywhere and everywhere works, here’s a few you may not have tried.

Masturbate watching and/or touching each other.
Tell him when you’re ready and have him shoot cum on the outside of your body and enjoy the heat of his hot juices as you achieve your orgasm. Or if you want penetration, insert your finger inside yourself with his penis. You’ll both enjoy the extra tightness this creates and you can move your finger around for added pleasure.

Stuck in traffic?
While your partner is in the driver’s seat and you’re lounging in the passenger seat, why not put on a little peep show. All you need, is to wear a dress or skirt and a thong for easy access. Spread your legs and finger yourself. (Discreetly or not...if other people look in your car, well, that’s what they get for looking!)

Bored, at a party.
Have a secret sign with your partner that lets him know your in need of his attention in private. If you can find a secluded spot where no one can see you, perfect. After all you only want him watching what you’re doing. Tell him to keep a look out for people (you know he’ll watch you instead). If you can’t find the seclusion you need for him to watch, but you have privacy yourself (staying at the table, while everyone else is dancing) simply whisper in his ear, what you’re doing to yourself and how good it feels.
